Was under the influence of bourbon earlier. 

"Interest income" registered differently - as in "the partner's share of income from his partner interest."

Anyway, interest income generated from loans secured by CA real estate is CA source.  You probably knew that.

For interest (or other income not subject to CA tax), go to Screen 43, Other Form,  CA Sch K-1 Col (e) (4th item for CA in the top window on the left "St. Other Forms".

Highlight the partner under second window on the left "Partner" .  For each type of income, enter the partner's share.  enter -1 for zero.
